Features: • BLx7080 can be used with any motion controller, PLC indexer or other controller that generates pulse and direction commands, or can be set to perform preset moves or jog functions. • Direct 120/240 volt, 50/60 Hz AC input. No external Power Supply needed. • Continuous current of 7A, peak current to 14A. • Speeds to 6,000 rpm. Motor and load dependent. • 20 kHz precision PWM amplifier. • Pluggable screw terminal connectors for AC power, motor phases, communications and I/O. • Pluggable, industry standard D connector for encoder and commutation signals. • Optically isolated RS-232. • Optically isolated I/O. • Internal regeneration clamp circuit. No external components needed. Options: • Five custom matched Applied Motion Alpha series brushless servomotors. • Standard or custom length extension cables. • Complete system configuration ordering. |
Description: The BLx7080 programmable servo drives include a motion controller, digital PID position loop, amplifier and 80 volt power supply. These features makes it suitable for a wide range of motion applications using either brush or brushless motors. The BLx7080 accepts pulse and direction commands from any type of motion controller, and also includes preset moves and jog capabilities. The BLx has seven inputs and one output. Tuning the PID loop is easy with our Quick Tuner software, which features a built-in oscilloscope. Software selection of encoder line count and commutation sequence allows the motor to be configured without swapping wires.
